Abstract

The present invention relates to a developing apparatus, including: a developing agent carrier for carrying a developing agent to develop an electrostatic latent image formed on an image carrier with the developing agent; a regulating member for regulating a thickness of a layer of the developing agent carried by the developing agent carrier; and a securing member, provided with an engaging hole for engaging with an axis, for securing the regulating member to a main body of the developing apparatus. The securing member is provided with a cutting portion formed around the engaging hole so as to be able to absorb, in a longitudinal direction of the regulating member, a difference between elongation and contraction of the regulating member and elongation and contraction of the main body of the developing apparatus.
